ABB25DHFN

Overview

The ABB25DHFN is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows with a 0.050 inch (1.27 mm) contact spacing. The connector utilizes hairpin bellows contacts made of beryllium copper with a gold plating thickness of 10.0 µin (0.25 µm). Designed for surface mount installation, it accommodates a board thickness of 0.062 inches (1.57 mm). The housing is constructed from black polyphenylene sulfide (PPS), supporting an operating temperature range of -65°C to 150°C.

Feature Summary

• Dual-edge female configuration with hairpin bellows contact type for reliable signal transmission
• Surface mount termination method compatible with automated assembly processes
• Gold-plated beryllium copper contacts ensure corrosion resistance and low contact resistance
• Polyphenylene sulfide insulation provides high thermal stability and mechanical strength

Applications

• High-density circuit board interconnections
• Edgeboard mounting systems
• Industrial control modules requiring robust surface mount connectors
• Telecommunications equipment backplanes

Procurement Notes

Verify the specific suffix 'FN' confirms surface mount installation rather than through-hole variants. Confirm RoHS3 compliance status as required by project specifications. Ensure the supplier provides official datasheets matching the manufacturer part number to validate contact material and plating thickness specifications before finalizing procurement orders.

Selection Notes

Select this component when surface mount technology is required for dual-edge card connections. The 0.050 inch pitch suits applications needing moderate pin density without excessive board space consumption. Verify that the target PCB design supports the specified 0.062 inch board thickness constraint and aligns with the black PPS housing color requirements for visual identification or aesthetic consistency.

Part Context

This model belongs to the ABB series of high-density card edge connectors from Sullins Connector Solutions. The series offers various position counts and mounting styles. The ABB25DHFN specifically addresses needs for surface-mounted dual-edge interfaces, distinguishing itself from through-hole alternatives like the ABB25DHRN within the same product family lineup.

Replacement Considerations

Direct substitutes include other Sullins models with identical electrical parameters but different mounting types, such as ABB25DHRN for through-hole applications. Cross-manufacturer replacements require matching the 0.050 inch pitch, 50-position count, and dual-edge female configuration while verifying mechanical footprint compatibility.
